Surfaces which possess extraordinary water attraction or repellency depend on surface energy, chemistry, and nano- microscale roughness. Synergistic superhydrophilic-underwater superoleophobic surfaces were fabricated by spray deposition of nanostructured TiO2 stainless steel mesh substrates. The coated meshes then used to study gravity driven oil-water separation, where only the from mixture is allowed permeate through mesh. Oil-water separation efficiencies up 99% could be achieved pore...
A facile synthesis method for highly stable carbon nanoparticle (CNP) dispersion in acetone by incomplete combustion of paraffin candle flame is presented. The synthesized CNP the mixture graphitic and amorphous nanoparticles size range 20-50 nm manifested mesoporosity with an average pore 7 a BET surface area 366 m2g-1. As application this material, was spray coated (spray-based coating) on glass to fabricate superhydrophobic (water contact angle > 150° sliding < 10 °) surfaces. surfaces...
Si/TiO<sub>2</sub> heterojunction photocatalyst was synthesized <italic>via</italic> a facile hydrothermal reaction and exhibits high photocatalytic activity towards conversion of CO<sub>2</sub> to methanol.
Superhydrophilic and underwater superoleophobic surfaces were fabricated by facile spray coating of nanostructured WO3 on stainless steel meshes compared its performance in oil-water separation with ZnO coated meshes. The gravity driven system was designed using these as the media it noticed that mesh showed high efficiency (99%), pore size 150 µm, whereas failed process when exceeded 50 µm size. Since, is a well known catalyst, simultaneous photocatalytic degradation organic pollutants...
A photo-responsive TiO2-coated stainless-steel mesh membrane (TiO2@SSM), possessing unique surface wettability, was fabricated. This TiO2@SSM is found to be capable of separating oil and water from oily has the potential carry out photocatalytic self-cleaning and/or degradation organic pollutants present in water. The fabrication quite simple: titanium dioxide (TiO2) nanoparticles were spray-coated onto stainless steel microporous (SSM) substrates annealed at temperature 500 °C. fabricated...
Abstract Chemotherapy, the most commonly used therapeutic method for cancer, has inherent constraint of low bioavailability. A number physical cancer treatments like radiation, ultrasound, photo-acoustic/photo thermal, microwave therapies are based on locating afflicted sites with help imaging, but serious drawbacks these treatment options that they damage neighboring normal tissues and/or induce undesired metastasis. In addition, methods very expensive and not in reach a common man...
The large-scale applications of cadmium sulfide (CdS) nanoparticles (NPs) as a photo-catalyst are limited by their poor stability (high aggregation tendency) and consequent reduction in the surface area increased rate recombination photoinduced electron-hole pairs, despite its inherent positive feature being visible light active. It has been reported that photocatalytic performance CdS can be considerably improved if is made composite material with reduced graphene oxide (rGO) an optimum...
